From the Scientific American article "Alone in the Milky Way," explain why life is less likely to thrive on planets orbiting stars that are further from the center of the galaxy.
From the Scientific American article "The Permafrost Prediction," if the permafrost in a given region thaws, some Carbon will be released from the soil, but it is also true that the same region will absorb more Carbon from the atmosphere. (a) Explain why, and (b) explain whether the net result is more Carbon added to the atmosphere or more absorbed from the atmosphere.
From lecture, normally, when a comet's orbit is different than we expect, it is because of something like the Yarkovsky Effect mentioned in question 6.19. Explain two reasons why we do not believe cometary jets are the cause of Oumuamua's peculiar path through the solar system.
From lecture, (related to Q1.9) use a graph of blackbody radiation to help explain why gases that block infrared light tend to warm the Earth due to the nature of the incoming and outgoing light (the blackbody curves).
From the video "Life Beyond Earth, Part 1," Freeman Dyson explains that there are two possibilities regarding the origin of life. Either it came into being gradually through chemistry and steps we could hope to retrace (and could presumably be reproduced elsewhere) or life is some kind of extraordinary fluke. If the answer to the question of the origin of life is the first possibility, what does that imply about life beyond Earth? What if the answer is the latter possibility?
From the video "Crash Course: Saturn," explain what properites of the lakes on the surface of Titan make us think there is active weather in the atmosphere of Saturn's moon Titan.
